   @kishoreg Oh, so we want the new behavior where we return the correct result 
until the threshold and return the approximate after threshold. In that case, 
using `distinctcounthll` will not work and I would +1 on Jackie's approach. 
That will achieve both. (1. keep the default behavior 2. add the ability to 
override the default behavior for advanced admin)
   
   @Jackie-Jiang How will you deal with the new input 
`hllLog2m=8;hllConversionThreshold=10` when we fall back to the new function 
with config? The original distinctcount function currently doesn't get the 
second parameter.
